Two volumes of air are separated by a thin rectangular heater (0.2 cm x 15 cm x 2 cm). The volumetric heat generation associated with the heater is 350 kW/m3. What is the temperature of the heater at steady state? The air in the bottom chamber is at (TB = 20 °C, hB = 15 W/m2.K) while the air in the top chamber is at (TT =55 °C, hT = 9 W/m2K). hint: for such thin application, we shall assume the same surface temperature on both sides of the heater.
